Hi can you help me with #7 on pg. 48?
Can you help me with the plugging in question 8 on pg. 29?
Can you help me on the backsolving question 7 on pg. 37? Its got me stumped even with the backsolving.
Hi! For page 120 question 8 in the pwn book, is there any other way to find the answer without using a Calculator? I tried using a calculator but it took me a long time to find the answer. In addition, is there any other way to find that there is only one solution other than graphing or plugging the x values back into the equation?
Hi! How do you do question 2 on page 100 from the functions section? I reviewed the solution in the back of the book but still don’t understand.
Hi! On q8 page 149 (polynomials), what is happening in D? Why is it true?
Hi Mike! In SAT official test 1, Q 29 (in the math calculator section), how do you solve this problem? I don’t quite understand the explanation/concepts mentioned in the book.
29)For a polynomial p(x), the value of p(3) is -2. Which of the following must be true about p(x)?
A) x-5 is a factor of p(x).
B) x-2 is a factor of p(x).
C) x+2 is a factor of p(x).
D) The remainder when p(x) is divided by x-3 is -2.
(Also what does PWN stand for?)

Hi, is the fourth edition math guide is relevant to the 2021 and 2022 SAT? Thank you for answering!
HI Mike…Thanks for all your help ! Here’s another question:
When a buffet restaurant charges $12.00 per meal, the number of meals it sells per day is 400. For each $0.50 increase to the price per meal, the number of meals sold per day decreases by 10. What is the price per meal that results in the greatest sales, in dollars, from meals each day?
Hi Mike… QAS March 2021, Section 3, # 20. Since “no solution,” can you consider each side a separate parallel line & use corresponding coefficients to confirm that k must equal 1/2? Or, what’s the best way to solve?
1/2x + 5 = kx + 7
In the given equation, k is a constant. The equation has no solution. What is the value of k?
Hi Mike …can you solve & explain? (from QAS March 2021)
Section 3; #11.
y = (x-1)(x+1)(x+2)
The graph in the xy plane of the equation above contains the point (a,b). If -1 < or = a < or = 1, which of the following is NOT a possible value of b?
Hi, Mike. How would you say the two math sections of the SAT are different (besides the obvious calculator use and the timing/number of questions)? I’m thinking in terms of content covered, types of questions, etc. Thanks!
Hi! Love your book so far. I just started reviewing. I looked at number 10 in the first section on page 29 and I was wondering how would you pick the correct answer if you chose to substitute 8 for d? Because both answer choices a and d work. Would you just try all the answer choices and choose different variable values and try again or is there a different way to approach it?
